The history of that was the ioctl was originally EXT4_IOC_GETFLAGS and
it was later generalized to be FS_IOC_GETFLAGS.  In this case though
we started with it being an generalized interface, so there's no need
to create an EXT4_IOC_TRIM ioctl.  I'll fix that up in your patch when
I add it to the ext4 patch queue.
